WRIST-WATCH CASE AND CLAMP.

Specification of Letters Patent.

Patented J an. 6, 1920.

Application filed July 29, 1918. Serial No. 247,142.

To all whom it may concern:

Be it known that I, DE FoREsT I-IULBURD, a citizen of the United States,residing at Chicago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Wrist-Watch Cases andClamps, of which the following is a description, reference being had tothe accompanying drawing and to the figures of reference marked thereon.

My invention relates to new and useful improvements in wrist watch caseand clamp.

The object of my invention is to provide a case for a wrist watch havingstrap clamping or holding means thereby enabling the use of a perfectlyplain piece of strap of leather, cloth or other material without itbeing necessary to sew or fix a buckle on the end of the strap orwithout sewing or forming loops in the strap or in any way having tomanipulate the strap itself other than to roughly form it into shapewhereby the same may be readily replaced when broken.

Another object of my invention is to provide a case for a wrist watch,in which the attaching strap forms a guard to prevent the watch casefrom coming into contact with the arm.

Referring now to the drawings Figure 1 is a top plan View of my improvedwrist watch case and clamp;

Fig. 2 is a bottom plan view of Fig. 1;

Fig. 3 is a transverse sectional view, showing the strap in its positionwhen applied to the wrist; and

Fig. 4 is a perspective view of the clamp.

Applicant is aware that wrist watches have been formed with ears onopposite edges for the reception of attaching strap, but in all suchwatches, it has been necessary to have a buckle or a clamp of some sortfastened to the end of the strap. In such a structure when the strapbreaks, it is necessary in replacing it to sew or otherwise fasten oneend of the strap to the watch case and secure the buckle or clamp to theother end of the strap.

In my device a perfectly plain piece of strap is used and, therefore,can be made and attached by anyone without the use of instrumentsotherthan scissors'or a knife for properlv shaping the strap.

Referring now to the drawings, 1 represents the watch case, which is ofthe usual form. It has 011 opposite edges the ears 2 and 3. The ear 2 isprovided with a clownwardly turned outer end 4 extending at an obtuseangle and the lower end extending below the plane of the lower face ofthe watch case. Said oblique portion has an elongated transverse opening5. The ear 3 is provided with a downwardly turned outer end 6, having aslot 7, which is of a length considerably greater than the opening 5 inthe ear 2. The ends of the downwardly turned portion 6 are thickened, asindicated at 8, and in them is pivotally mounted the clamp 9 whichfirmly holds the strap when passed through the slot 7 as fully shown inFig. 3 of the drawings.

The attaching strap comprises a rounded enlarged portion 10, of a sizeand shape slightly greater than the watch case, to form a guard toprevent the case from coming into direct contact with the wrist. Thestrap portion 11 passes outwardly through the slot or opening 5 andaround the wrist, the enlarged body portion preventing the strap fromslipping through the opening 5. The end of the strap is then passedthrough the slot 7 from the inside and the clamping member swung down onthe strap and the same is prevented from being withdrawn from the slotand the watch case firmly held upon the wrist.

WVhile I have shown and described a pivoted clamping member for lockingthe free end of the strap to the case, it will be un derstood that thesame could be varied and any form of holding means employed with outdeparting from the spirit of my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A wrist watch holder comprising a case, an outwardly extending earcarried by one edge of the Watch case having an obliquely extendingouter end provided with a slot, an ear carried by the opposite edge ofthe case and having an obliquely extending outer end, a clamp in saidobliquely extending end, and an attaching strap having an enlargedportion forming a guard for the lower face of the case and having astrap portion passing through the slot in the ear and adapted to bepassedthrough the clamp as shown.

2. A wrist watch holder comprising a case having slotted ears, a jawpivoted within the slot of one of said ears to form opposed clampingjaws, a wrist band passing freely through one of said slotted ears andprovided-with an enlarged portion incapable of passing therethroughwhereby said band is attached to said ear, the free end of said bandbeing adapted to pass between the jaws of said other ear and to beadjustably clamped thereto.

3. A wrist watch holder comprising a casing provided with an aperturedmeans, and a band fastening means, a wrist band adapted to pass freelythrough said apertured means and provided with an enlarged portionsubstantially covering the back of said casing and incapable of passingthrough said apertured means, the free end of said band being adjustablysecured to said casing by said fastening means.

4. A wrist watch holder comprising a casing provided with aperturedmeans and a substantially opposed band securing means, a wrist bandadapted to pass freely through said apertured means and provided with anenlarged portion incapable of passing through said aperture whereby saidband is fastened to said casing, the free end of said band beingadjustably secured to said casing by said band securing means.

5. A wrist watch holder comprising a casing provided with opposed ears,one of said ears being slotted, a Wrist band adapted to pass freelythrough said slot and provided with an enlarged portion incapable ofpass ing therethrough whereby said band is attached to said ear, saidsecond ear being provided with a fastening device to receive the freeend of said band and hold the same in adjusted position.

In testimony whereof I aflix my signature in the presence of twowitnesses.
